I received my Slik Stik and I really love it.
It has the same problem as the TAC-2 though, pressing the fire button too much or trying to hold it for long hurts the thumb part of your palm a lot (Try playing R-Type 2 or another shmup). I tried holding it with my right hand instead like a leftie, and it helped a bit but it's awkward because I have to hold the joystick from the front part to be able to press the fire button.

Construction is solid as fuck like with the TAC-2, this thing can never break. By being smaller I do like the shorter response time. The stick is really really neat.

I wonder if there's any modification I can apply to the joystick button. Perhaps it would benefit from a microswitch replacement.
